  1. 41. An evaluation of the treatment performance of a ten year old stormwater biofilter in Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Sara Eklund; [2020]
    Keywords : Biofilter; Water Quality; heavy Metals; Nutrients; Stormwater Treatment; Sweden; Tyresö; Biofilter; Vattenkvalitet; Tungmetaller; Näringsämnen; Dagvattenrening; Sverige; Tyresö;

    Abstract : Urban runoff may be contaminated with, for example, metals, nutrients and sediment. Generally, such runoff enters waterways and oceans without any type of treatment. Bioretention systems can be used to protect the aquatic environment since one of their main objectives is to remove pollutants from stormwater. READ MORE

  3. 42. Nutrients spreading with cloudburst modeling

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Nikita Smiyanov; [2020]
    Keywords : MIKE21; 2D-modeling; nutrients; phosphorus; nitrogen; cloudburst; land-use; MIKE21; 2D-modellering; närsalter; fosfor; kväve; skyfall; markanvändning;

    Abstract : Climate change and environmental disasters are strongly dependent. Humanity is facing considerable changes in environmental adaptions and remediation of contaminated sites. Water is a valuable resource that should be protected and prevented from hazardous influences. READ MORE

  4. 43. The role of groundwater in the inundation of a river-connected floodplain : case study of the river Silverån in southeast Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Stina Bång; [2019]
    Keywords : Groundwater flooding; Groundwater modeling; Flood modeling;

    Abstract : Fluvial flooding has long been recognized as one of the most frequently occurring natural disasters worldwide, with consequences as large economic losses from damages on infrastructure and agriculture, as well as severe impacts on human health. A less known and explored type of flooding is groundwater flooding. READ MORE

  5. 44. High resolution modelling and analysis of urban flooding

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Angelos Kosmas; [2019]
    Keywords : Tokyo Storm Runoff model; TSR; urban flooding; Augustenborg; stormwater management; pipe networks; Technology and Engineering;

    Abstract : The predictions on climate change and precipitation patterns in the near future, as well as urbanization, lead to higher volumes of runoff, which in turn challenge the sustainability and functionality of urban drainage pipe networks. In order to understand how these changes will affect the existing infrastructure in urban areas, integrated urban water model software are needed to identify effective solutions to minimize urban flooding.

  6. 45. Runoff modelling and assessment of treatment wetland performance using a triangular form based multiple flow algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Clara Hübinger; [2019]
    Keywords : Earth and Environmental Sciences;

    Abstract : Eutrophication is one of the biggest threats to aquatic ecosystems. As nutrient load increases in marine environments in the Öresund and Baltic Sea and dead zones grow, Swedish municipalities further their efforts in limiting the amount of nutrients delivered into those environments.
